The method of step-by-step packing is adopted to generate the three-dimensional grain morphology typical for these materials. Crystal plasticity finite element simulations of uniaxial tension are performed for two models with random and cube-textured columnar grains inherent in selective laser melting. Comparative analysis of the computational results shows a substantial difference between the microscale stress and strain fields. The presence of cube-textured columnar grains provides more homogeneous stress-strain distributions inside the melt pools and unloads the adjacent regions of fine equiaxed grains, thus reducing high stress concentration in them UR - http://vital.lib.tsu.ru/vital/access/manager/Repository/koha:000895500 ER -
